Gokai helped a U.S. signage manufacturer improve channel-letter production with custom cast acrylic sheets featuring better flatness, optical clarity, thickness control, color consistency, and protective-film performance. The cooperation reduced scrap, improved illuminated sign quality, and supported reliable outdoor retail-signage projects.

Gokai partnered with a U.S. signage manufacturer to solve acrylic sheet issues including yellowing, low clarity, and inconsistent thickness. By providing UV-resistant cast acrylic with 92% light transmittance and precise tolerances, Gokai became the client’s exclusive supplier, enabling stable production and market expansion.

A European luxury retailer faced color inconsistency, yellowing, and edge cracking in bulk acrylic sheets due to recycled material use and improper processing. By switching to 100% virgin material, applying annealing, and improving cutting and polishing, defects were eliminated. Light transmittance stabilized, product quality met premium standards, and the client required certified material and batch testing for future orders.

A Saudi furniture factory faced severe chipping, cracking, and high scrap rates when processing 20 mm PVC foam boards due to uneven foaming and low density. Upgrading to high-density, uniform, high-toughness boards resolved the issues, delivering smooth cutting performance and reducing scrap rates below 2%, enabling stable production and continued bulk orders.
